HEAT DiSTR'IBUTOR FOR REGISTERS Original F'iled Oct. 10 1 931 INVENTOR Patented May 26, 1936 UNITED STATES PATENT OFFICE tober 10, 1931. 1935, Serial No. 47,514

7 Claims.

This application is a substitute for my application for the same subject-matter, Serial No. 568,015, filed October 10, 1931.

My present invention relates to heat-distributors for deflecting hot air issuing from registers, so that the walls of the room are kept clean.

In houses heated by hot-air, it is most convenient, for many reasons, to place the register or hot-air distributor in the floor, and near the corner of the room, or at least near one sidewall of the room. This practice has been subject to the disadvantage that it causes the adjacent wall or walls to become dirty very quickly, and it requires more floor space than it should, because furniture cannot be placed close alongside of the register because of the heat and dirt.

It is the principal object of my invention to provide a readily insertable means, that may be inserted, out of sight, in the outlet-chamber under the register, and that will strain the hot-air blast and at the same time deflect it away from one or two of the sides of the register, so as to keep it away from a wall or a piece of furniture.

It is a further object of my invention to provide such a device in a form which is of the utmost simplicity, and yet which is sturdy, inexpensive, and capable of assembly with the baflie or deflector member or members on any side or sides desired.

With the foregoing and other objects in view,

my invention consists in the structures and combinations hereinafter described and claimed, and illustrated in the accompanying drawing, wherein Fig. 1 is a transverse sectional view of my attachment, the section-plane being indicated by the line I-I of Fig. 2,

Fig. 2 is a top plan view of my attachment, and

Fig. 3 is a sectional elevational view, on a section-plane indicated by the line III-III in Figs. 1 and 2, showing my attachment in place under a register.

As shown in the drawing, my attachment is intended to be used in hot-air heating systems utilizing a furnace-pipe 4 delivering hot air to a room through a register 5 which covers the top of the outlet-chamber 6 in the floor I. In accordance with the usual arrangement, the register 2 is shown close to one o fthe side-walls 8 of the room. 50 My attachment is designed to fit within the outlet-chamber 6, where it can be placed by the simple process of lifting off the register, and where there is plenty of room for a deflector having a height of several inches, without interfering at all with the register.

This application October 30,

My attachment consists of a fine-mesh screen 9 which is firmly held and supported by a rectangular sheet-metal frame or binder ll surrounding the screen. The screen cleans the air, and the binder performs the double function of holding the screen and supporting one or more inclined sheet-metal air-distributors or baffles I6 and IT which are preferably provided, on their lower edges, with tabs I8 which poke through holes or slits l9, and are bent under, as shown.

In the ordinary course of manufacture, the screens 9, with their binders H, are usually stacked up without any deflectors [6 or I! on them, and stacks of deflectors, of several sizes and shapes, are also kept on hand. Then, when orders are filled, it is a simple matter to attach any desired combination of baffles required by the customers, so that my attachment will be suitable for right-hand corners, left-hand corners, singledeflector service for rooms in which the hot-air blast is to be diverted from only one wall or piece of furniture, etc.

My invention costs very little, is no trouble to put in place, occupies no space that would otherwise be used, is quite out of sight and out of the way so that it cannot be tripped on, and both strains the air and catches the dirt, while deflecting the air away from walls or furniture which would otherwise be dirtied or damaged by the heat.

While I have shown my invention in one form of embodiment which is at present preferred, it will be obvious that various changes may be made without departing from the essential substance and spirit thereof. I desire, therefore, that the 35 appended claims be accorded the broadest construction consistent with their language and the prior art.

I claim as my invention:

1. In a hot-air heating system, a room having a floor register, means for providing an outletchamber under the register, a hot-air furnace pipe communicating with the bottom of said outlet-chamber, and a separate attachment disposed in said outlet-chamber, between the pipe and the 45 register, and spaced from the latter, said attachment comprising a frame having an inclined solid impervious bafiie extending upwardly and inwardly from at least one side edge of the frame.

2. In a hot-air heating system, a room having a horizontal floor register, means for providing an outlet chamber under the register, a hot-air furnace pipe communicating with the bottom of said outlet chamber, and a separate attachment disposed in said outlet-chamber, between the pipe and the register, and spaced from the latter,

said attachment comprising a screen for cleaning the air and a frame having a portion carrying said screen and having an inclined, fixed, impervious portion constituting a bafile extending upwardly and inwardly for deflecting the hotair blast away from one or more side-edges of the register.

3. A hot-air attachment of a size commensurate with hot-air registers, comprising a screen and a frame surrounding said screen, said frame having an inclined solid impervious bafile extending upwardly and inwardly from at least one side edge of the frame, said baflie having flexible metal tabs on its bottom edge, and said frame having slits therein, on all sides, so that said tabs may be inserted and bent over, to support said baffle on any desired side of said frame.

4. A hot-air heating system having means for providing an open outlet-chamber, a register covering said outlet-chamber on one side, and a furnace-pipe communicating with said outlet- 'chamber on another side, characterized by having two inclined baflles, in said outlet-chamber, for deflecting the hot-air blast away from two adjacent side-edges of the register.

5. A hot-air heating system having means for providing an open outlet-chamber, a register covering said outlet-chamber on one side, and a furnace-pipe communicating with said outletchamber on another side, characterized by having a removable attachment in said outlet-- chamber, said attachment comprising a screen for covering the end of the furnace-pipe, and a frame having a solid, fixed, impervious portion thereof extending in the direction of air-flow towards the register and inwardly with respect to the frame, so as to act as an inclined baiile for deflecting the hot-air blast away from one or more side-edges of the register.

' 6. A hot-air heating system having means for providing an open outlet-chamber, a register covering said outlet-chamber on one side, and a furnace-pipe communicating with said outletchamber on another side, characterized by having a removable attachment in said outlet-chamber, said attachment comprising a screen for covering the end of the furnace-pipe, and two in clined baflies for deflecting the hot-air blast away from two adjacent side-edges of the register.

"7. A heat deflector comprising an open rectangular frame, a screen secured therein, and 'a pair of flat, sheet-metal baffles secured to two adjacent sides of said frame, each bailie extending at an acute angle upwardly and inwardly from its side of the frame. I
